Ortgies & Company made only pistols chambered for 7.65mm Browning (.32 ACP), though it is clear that Heinrich Ortgies, from the beginning, also intended to produce pistols in 9mm Browning Short (.380 ACP) and 6.35mm (.25 ACP).
falsetto - a male singing voice with artificially high tones in an upper register. 1  head register, head tone, head voice - the higher ranges of the voice in speaking or singing; the vibrations of sung notes are felt in the head. 2  high-pitched, high - used of sounds and voices; high in pitch or frequency.
The type of vocal cord vibration that produces the falsetto voice precludes loud singing except in the highest tones of that register; it also limits the available tone colors because of the simplicity of its waveform. Modal voice is capable of producing much more complex waveforms and infinite varieties of tone color.
